Fitting OEM CD changer to MFD2 - extra wire???

[York_GTI]

I'm fitting a CD changer to my armrest today and have all the bits including the correct cable. 

The changer cable however has a seperate loose brown wire that connects to the block at the headunit end - any idea what this is for and if I need to connect it?

Any help would be appreciated

It's an ground wire.

Thanks Steve

Any ideas of a suitable place to attach it?  I take it the changer won't work if I leave it unconnected?

All fitted and working perfectly

York-gti, did you have to code the cd changer?

[York_GTI]

Sorry for the delay - it was a plug and play job and works perfectly with no coding

Don't suppose you have a PN for the cable leading from your CD changer to the back of your HU do you?

Unfortunately not - I think I got it from eBay
